Authorities say a body has been found at the Southern California lake where “Glee” star Naya Rivera has been missing since last week. The Ventura County Sheriff’s Office says in a tweet that the body was found Monday morning at Lake Piru. There’s no information on whether the body has been identified but authorities plan an afternoon news conference. The “Glee” star disappeared July 8 after she took her young son out on a rented boat.

THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.

A member of a team searching a Southern California lake for a missing TV star said Sunday that he's confident his crew is getting a clearer idea of where in the lake to find her, a magazine reported.

Robert Inglis of the Ventura County Sheriff’s Office Search & Rescue Team told Us Weekly that Naya Rivera sent to a family member a picture of her 4-year-old son, Josey, in front of a cove before she disappeared July 8 after diving into Lake Piru.

“There was a picture sent to a family member that showed the boy on the boat by a cove,” Inglis told the magazine. “We found where that cove was.”

A time stamp on the photo shows it was taken 90 minutes to two hours before the boy was found alone on the pontoon boat, the magazine reported.

Inglis told Us Weekly that the area where the photo was taken and the spot where the boat was found were starting points for authorities before the search was expanded.

“We did send our dive members to those two locations and searched those extensively,” he told Us Weekly.

Rivera remained missing as of Sunday night.

Authorities said Thursday they believe Rivera, 33, drowned. Her son was found the boat.

The boy told investigators that he and his mother went swimming and he got back on the boat, but “his mom never made it out of the water,” Sheriff’s Sgt. Kevin Donoghue said.

Rivera began acting at a young age, but she rose to national attention playing a lesbian teen on “Glee,” which aired from 2009 until 2015 on Fox.

This story corrected Rivera's son's name to Josey.
